The anti-CD33 monoclonal antibody linked to NAc-gamma calicheamicin gemtuzumab ozogamicin (CMA-676) was used to treat a patient with Philadelphia/bcr-abl-positive acute myeloid leukaemia. We report a morphological and cytogenetic complete remission after treatment with two doses of gemtuzumab ozogamicin as a single agent. Using real-time polymerase chain reaction (PCR), gemtuzumab ozogamicin treatment resulted in a 3-1og tumour mass reduction in bone marrow.
